Hematocrit and Plasma Biochemical Data for Sea Turtles in Florida

Logos of organizations sponsoring this research

To monitor the physiological status of wild populations of sea turtles to ensure recovery of these threatened and endangered species, baseline hematocrit and blood biochemical reference intervals need to be established.

To accomplish this recovery goal, we have developed a multidisciplinary collaboration that includes the College of Veterinary Medicine (University of Florida), the Archie Carr Center for Sea Turtle Research (University of Florida), the St. Lucie Power Plant (Florida Power and Light Corporation), the Marinelife Center of Juno Beach, and the Clearwater Marine Aquarium.

Our research project is funded by the Florida Sea Turtle Grants Program.

Sea Turtle License Plate

Throughout the year, as sea turtles enter the Port St Lucie Power Plant canal system, they are removed, weighed, measured and tagged prior to release in the nearby Atlantic Ocean. Approximately 800 to 1000 turtles are removed per year. While most of the turtles caught in this system are green turtles (Chelonia mydas) and loggerheads (Caretta caretta), hawksbills (Eretmochelys imbricata), Kemp’s ridleys (Lepidochelys kempii) and leatherbacks (Dermochelys coriacea) also are trapped and removed.

We collect blood from all sea turtles that are caught in the St. Lucie Power Plant canal system and determine reference baselines for hematocrit (packed cell volumes, PCV) and for plasma biochemicals. Additionally, plasma protein electrophoretograms allow for the determinations of the following protein fractions: pre-albumin, albumin, alpha globulins, beta globulins, and gamma globulins. We update the data presented at this website at regular intervals.

What is this view?

You are using a dynamic assistive view of the University of Florida site. It has all the same data and features of the original site but formatted just with assistive users in mind. It has links and content reorganized to aid assistive users and has controls at the bottom under assistive options that allow you to control key aspects such as font size and contrast colors etc.
This is not a separate text-only site, it's a dynamic view that uses unique technology from Usablenet to give assistive users better, more accessible access to the same content and features as all users that use the graphic view of the site.
